General Considerations About DID Numbers
A Direct Inward Dialing number, also abbreviated as a DID number is a virtual phone number that behaves as a local one for residents of a given region or country. Such numbers can function either over a SIP trunk connection (via the Internet) but also by forwarding to a PSTN (a traditional phone network). Thus, this can effectively allow a company/party to establish local numbers in all regions of interest throughout the world while allowing local residents to conveniently call the party/client.
Given that DID numbers can be routed via the Internet (over long distances) and then interconnected with the local landlines/mobile networks, these can come with huge savings when compared to traditional international or inter-regional dialing. In fact, it is this fact that makes the technology viable and so actual (given our globalizing world). To learn more about the service package offered and to obtain your own DID number, visit site of a top provider, where you can learn about the technical possibilities, conditions, prices, etc.
A company that adopts DID numbers does not have to be physically present in all the areas of interest to be able to effectively communicate with its clients/partners. In fact, employees could be concentrated in a limited number of locations, enabling huge infrastructure- and logistics-related costs, while preserving an impressive national, regional, or global outreach. This is especially relevant for smaller companies, that are limited in their resources.
Finally, another great advantage offered by DID numbers is that they enable flexible assignment of individual phone numbers to specific employees, departments, etc. without the need to adapt the physical infrastructure each time such changes are made (this is part of the reason these numbers are called virtual). The number of communication channels could be also dynamically scaled up and down as needed for each number.
Choosing A Suitable Provider
There are several desirable features/options that a good provider is expected to make possible for its clients:
- low latency for inbound and outbound calls – this is a direct function of the quality of the infrastructure accessible and the efficiency of interconnection with national/regional carriers. Although calls routed via the Internet are characterized by some degree of latency, this does not have to be disruptive and with good infrastructure, it should not be the case.
- maximum geographic coverage (both nationally and internationally). Obviously, the regions or nations covered must be the ones the company is interested in.
- support for local services, emergency calls, short code dialing, etc. (just like a national telephone network).
- dynamic channel capacity that could be flexibly scaled as needed.
- easy installation and support for SIP-based PBX devices.
Given the associated advantages, DID numbers present an effective step towards qualitative communication and global outreach that is by no means prohibitive in cost. Opting for a good provider can help make the best of this technology.
